So one of the products is a free viewer which is a taster of what the software can do with reduced functionality, I make no revenue from the free viewer but hope to upsell the product to people who show an interest.
So this weekend I have been running a ppc for the free pdf viewer and today for example have had 128 ppc clicks!
So the customer lands on a page that says would you like free download then click here, of the 176 page views showing for the landing page (no other way of finding it other than the ppc) 91 people clicked to the next page, which asks for your name and email address, and when filled in you get sent the link by return.
Phew

Anyway when you get to the email page I have today introduced that you will be entered into a monthly draw for an ipod shuffle for filling in your details.
Question would that be enough pull for you to sign up?
